    T cell self-reactivity during thymic development dictates the timing of positive selection

    Lydia K Lutes et al.
    Developing T cells whose TCRs have relatively low reactivity experience very brief TCR signaling events, experience delayed positive selection, and retaina preselection gene expression signature as they mature.

    T cell immunodominance is dictated by the positively selecting self-peptide

    Wan-Lin Lo et al.
    The T cell repertoire can display immunodominance to an epitope as a result of optimal positive selection in the thymus by one self-peptide/MHC ligand.

    Use of signals of positive and negative selection to distinguish cancer genes and passenger genes

    László Bányai et al.
    In contrast with earlier conclusions, negative selection has a major role in cancer evolution.

    Immune genes are hotspots of shared positive selection across birds and mammals

    Allison J Shultz, Timothy B Sackton
    Pathogens, particularly viruses, target the same genes over deep evolutionary time, resulting in shared signatures of positive selection and transcriptional responses at the same genes.

    Filovirus receptor NPC1 contributes to species-specific patterns of ebolavirus susceptibility in bats

    Melinda Ng et al.
    NPC1 is a genetic determinant of filovirus susceptibility in bats, and some variations in bat NPC1 may reflect host adaptations to reduce filovirus replication and virulence.

    Natural selection and repeated patterns of molecular evolution following allopatric divergence

    Yibo Dong et al.
    The genomic architecture of allopatric species is a mosaic of many conserved genes and a few adaptive ones, reflecting balance between conservation of ancestral functions and evolution of new features.

    Compensatory induction of MYC expression by sustained CDK9 inhibition via a BRD4-dependent mechanism

    Huasong Lu et al.
    A new potent and selective CDK9 inhibitor induces the expression of the proto-oncogene MYC via a mechanism that depends on the bromodomain protein BRD4.

    Stochastic processes constrain the within and between host evolution of influenza virus

    John T McCrone et al.
    An analysis of influenza viruses from naturally infected people suggests a tight transmission bottleneck and little positive selection within hosts.

    Cryo-electron tomography reveals novel features of a viral RNA replication compartment

    Kenneth J Ertel et al.
    Cryo-electron tomography unveils striking new structural components of positive-strand virus RNA replication compartments, greatly advancing mechanistic insights into the structure, assembly, function and control of these critical complexes.

    Cryo-EM structure of respiratory complex I at work

    Kristian Parey et al.
    The site of ubiquinone binding observed in the cryo-EM structure of respiratory complex I during turnover supports a two-state stabilization change mechanism.
